Purpose: The purpose of this study was to determine the relative contribution of energy systems in a freestyle (FS) and a Greco-Roman (GR) wrestling match, quantity and quality of obtained scores, and the competition efficiency of winners in the 2017 Wrestling World Championships (WCh) through analysing the recorded videos of all the matches of this event. Material: The materials of the present study were 295 FS and 266 GR recorded videos of the 2017 WCh, a multimedia player (lap top) for watching and analysing them, and a chronometer for recording the different duration of activities happening during these matches. In addition, special papers were designed in advance to make sure that all the required data were recorded properly. Results: The percentages of ATP-PC (ATP), lactic (LAC), and aerobic (AERO) energy systems were 6.66, 62.74, and 30.60 in FS, and 5.94, 67.53, and 26.53 in GR. Quantity and quality analysis of scores showed that FS wrestlers significantly scored more 1and 4-point, while GR wrestlers were superior regarding the quality 2-point. The average competition efficiency of gold medallists was 18/43±4/67 in FS and 15/87±3/18 in GR which were statistically significantly greater than that of all other placers. Conclusions: This study showed the dominance of LAC in a wrestling match in both styles, although their relative contribution was significantly different between styles. In addition, FS wrestlers significantly scored more points, and Gold medallists demonstrated the greatest average competition efficiency compared to other medallists.

2017年摔跤世界锦标赛的时空分析

目的:本研究的目的是确定自由式(FS)和希腊-罗马(GR)摔跤比赛中能量系统的相对贡献,获得分数的数量和质量以及2017年摔跤比赛中获胜者的竞争效率世界锦标赛(WCh),方法是分析该赛事所有比赛的录像。资料:本研究的资料是2017年WCh的295 FS和266 GR记录的视频,用于观看和分析它们的多媒体播放器(笔记本电脑)以及用于记录这些比赛中发生的不同活动持续时间的天文钟。此外,事先设计了特殊文件以确保正确记录了所有必需的数据。结果:ATP-PC(ATP),乳酸(LAC)和有氧(AERO)能量系统的百分比分别为6.66、62.74和30。FS中为60,GR中为5.94、67.53和26.53。得分的数量和质量分析表明,FS摔跤手的得分分别为1分和4分,而GR摔跤手的质量得分为2分。金牌获得者的平均竞争效率在FS中为18/43±4/67,在GR中为15/87±3/18,在统计学上显着高于所有其他竞猜者。结论:这项研究显示了两种风格的摔跤比赛中LAC的优势,尽管两种风格的相对贡献显着不同。此外,FS摔跤手明显得分更高,与其他奖牌获得者相比,金牌获得者显示出最高的平均比赛效率。得分的数量和质量分析表明,FS摔跤手的得分分别为1分和4分,而GR摔跤手的质量得分为2分。金牌获得者的平均竞争效率在FS中为18/43±4/67,在GR中为15/87±3/18,在统计学上显着高于所有其他竞猜者。结论:这项研究显示了两种风格的摔跤比赛中LAC的优势,尽管两种风格的相对贡献显着不同。此外,FS摔跤手明显得分更高,与其他奖牌获得者相比,金牌获得者显示出最高的平均比赛效率。得分的数量和质量分析表明,FS摔跤手的得分分别为1分和4分,而GR摔跤手的质量得分为2分。金牌获得者的平均竞争效率在FS中为18/43±4/67,在GR中为15/87±3/18,在统计学上显着高于所有其他竞猜者。结论:这项研究显示了两种风格的摔跤比赛中LAC的优势,尽管两种风格的相对贡献显着不同。此外,FS摔跤手明显得分更高,与其他奖牌获得者相比,金牌获得者显示出最高的平均比赛效率。金牌获得者的平均竞争效率在FS中为18/43±4/67,在GR中为15/87±3/18,在统计学上显着高于所有其他竞猜者。结论:这项研究显示了两种风格的摔跤比赛中LAC的优势,尽管两种风格的相对贡献显着不同。此外,FS摔跤手明显得分更高,与其他奖牌获得者相比,金牌获得者显示出最高的平均比赛效率。金牌获得者的平均竞争效率在FS中为18/43±4/67,在GR中为15/87±3/18,在统计学上显着高于所有其他竞猜者。结论:这项研究显示了两种风格的摔跤比赛中LAC的优势,尽管两种风格的相对贡献显着不同。此外,FS摔跤手明显得分更高,与其他奖牌获得者相比,金牌获得者显示出最高的平均比赛效率。
